Well, I'm 16 and was diagnosed when I was 12, and my knee has continued to play up multiple times over the years after initially taking 12 months off sport. Last MRI showed that lesion was filling in but still there. (Originally size of 20cent AUS coin, now just over half the size)

I last saw my doctor in February of this year, and he only said to come back to see him if my knee locked or I had serious swelling....

He is meant to be one of the top orthopedic surgeons in Australia, so I trust him, so don't really know what to try next?
